I've been looking for an absolute orientation IMU (usually 9 axis, with accelerometer, gyroscope, and magnetometer) that can measure high g-loads in one direction (max ~20 g). However, the highest rating I can find is around 16g. I am aware that there are accelerometers with higher capabilities, but not of one within a single-chip IMU.
However - since the accelerations only appear significantly in one direction, I was thinking it I could rotate the chip by 45 degrees, so that the acceleration is "partially taken on" by two axes, giving me 16 * sqrt(2) ~= 22.5g (sufficient for my application).
Would this work in practice?
